TRANSMISSION OF WAVELET-CODED IMAGES OVER UNRELIABLE CHANNELS

During the past decade the wavelet transform was established as the most efficient tool for image compression. In this presentation, we will briefly review the two most popular trends in wavelet image compression (tree-based and block-based) and then we will discuss transmission aspects using several wavelet coding paradigms. Two main transmission scenarios will be presented: transmission over memoryless noisy channels and wireless channels. For each transmission scenario, we will examine the suitability of widely-used channel codes such as RCPC codes and Turbo-codes. Efficient channel coding optimization strategies will be proposed and evaluated using data collected from experiments.
